To all whom it my concern:

-Be it known.that-,I, Eon C. OLI VER, a citizen of the United States,resid1ng...at Detroit, 'county of Wayne, State of Michi- 5' an, haveinvented a, certainnew and useul Improvement in Resetting Devices, anddeclare the following to be afull, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had-to the accompanyingdrawings, which form apart of this specification. My invention relatesto a re-setting device for mechanical counters, and consists in the imrovements hereinafter described and polnted out in theclaim.

In the accompanying drawings :F1gure 1, is a plan view of so much of amechanical re-setting device as is necessary to illustrate my invention.Fig. 2, is a view similarto Fig. 1, the indicating disks being removedand some of the wheels being shown in a different position from thatindicated in Fig. 1. Fig. 3, is a View similar to Fig. 2, the portion ofthe casing shown being here indicated in section and the wheels shown ina different position from Figs. 1 and 2. Fig. 4, is a detail sectional.view, the section being taken on the line 4 -4. of Fig. 2, and the viewbeing from the right of the sectional plan. A, is the supporting platewhich is inclosed in a casing 13, only a small portion of the, casingbeing shown. 35 C, is a spindle, the revolutions of which are to becounted.

D, F, H, are sleeves adapted to turn on pintles extending verticallyfrom the suporting plate A. The sleeve D is actuated 40 y the pointer 0upon the shaft C; the sleeve F by a pointer d on-the sleeve D, and thesleeve H by a pointer f on the sleeve F in .the usual way.

a, is an indicating disk on the sleeve D which is the units counter.

a is an indicating disk upon the sleeve F which is the ,tens counter,and a an indicating disk upon the sleeve H which is the hundredscounter.

the distance traveled by an automobile and whenone has gone upon ajourney and returned, he wishes to know howfar he has been which isrecorded by the mechanical 55.counter, then he wishes to restore theindexes to zero in order that they shall. indi- Application ined June20, 1910. seriai r fusin e, "g, i, at such pointin eaclr of the piiii11s that all the cut away portions may,

teeth of said pinions.

My device is designed as an indicator of.

cate directly the. distance he has traveledon any subsequent journey;2T0 this end, -.-1I place pinions E, G, I, upon-the vsleeves, D, F, H,respectively, and Lcutaway a portion 6 of each of these-pinions,"asindicated-= at line, as indicated imFig 3.:HI-then pr H a series ofconnectedge'ar wheels M; N; secured upon sleeves J K','L, which unn fiupon pintles. extending-- vertically fro supporting plate A and solocatedtha w of said wheels shall intermesh with one [of the pinions E,G, I, except when the away portions of the latter are adjacent to lthe-wheels M, N, P, as indicated in Fig. I cut away a "portion of eachof the wheels M, N, P,'as indicated at m, n, p, sothaii when said cutaway. portions are adjacent to the pinions E, G, I, the teeth of the"gear wheels M, N, P, do not engage the This position is indicated inFig. 2.

.Q, R, S, are gear wheels on the sleeves J, K, L, the teeth of the gearwheels-Q, R; S,

" engage with each other and said gear wheels are continuous and not cutaway as arethe' gear wheels previously described." v

" T, is a push rod having a rack-Znpon a por tion of it. The push rod Tis a'dapted to reciprocate in hearings in the casing B and I on thesupporting plate A so that said push rod extends throughthe casing andmay be actuated from the outside thereof. Sp, is a retractingspring'iad'apted to actuate the push rod .T toward "the right, as shownin the drawing.

t, is a gear wheel connected with the sleeve K so that the rotation ofsaidgear wheels shall rotate said sleeve. The rack of the push rod Tengages the teeth of the-gear wheel 27. a

The operation of the above described device is as follows :When the rodTis in its normal position, as shown in Fig. 2, it is forced to the limitof its travel to the right,

instance, 'that indicated in Fig. 2. Now, if it is desired to re-set themechanism, the

' push rod T is pressed inward to the left to gear'wheels M, N,P,.t-urning freely to'the thelimit of its travel, as shown in Fig. 3.,

. by which motion all three of the gear wheels M, 'N,.P,-will berotated, and each of said vgear wheels will engage with itscorresponding pinion in theseries E, G, Land turn the latter until thecut away portions 0, g, i, come adjacent to the wheels M, N,

shown. Now when the push rod is released, it will. be retracted by thespring Sp, the

posit-ion indicated in Fig. 2, in. whic h the cut-away portions areadjacent to the pinions E, G, I,- and the latter'arenow free to turnindependent of the wheels M, N, P. The vpositions-of the pinions E, G,1, shown in Fig, 3,. correspond to the zero indicating positionsbf theplates a, a a (Fig. 1).

s, is a lug rising from the supporting frame A, and r, is alugtextending inward from the gear wheel R on the sleeve K. The lug 1-engages" the-lug s to limit the rotation of the wheel N at the positionshown in What I claim is A series of revoluble indicating parts, eachproceedingpart beingadapted to actuate the next following part, aportion of a of gear wheels adapted to engage a gearwheel on one of saidindicating parts so as to impartto the same its roper movement relativeto' the other indicating parts, the' cut away :portions'of said gearwheels having' the relative location described, said second seriesof'gear'wheel's being adapted to be actuated to restore the indicatingparts to position.

In testimony whereof, I sign this specification in the presence of'twowitnesses.
